So far the post hasn’t slipped. We bought the bikes with the thudbuster fitted, which along with the Gell saddle really increased the height for my wife. Looking at the Selle Toyal web site, I’m looking at two saddles (Respirio and Lookin 3D) with the 3D being more compact hightwise, but with elastomers attached. I’ll likely try that on my bike and see how my lady fairs with it too but the Respirio (relaxed) looks slightly more comfortable but higherHi and glad you're pleased with your Tinkers. Saddles are such personal things and I shall be putting my favourite Brooks leather one on the blue bike after tomorrow. The seat post on the blue one was also shortened by the dealer when supplied to ensure it would lower enough. However when I ride it I have the seat post a lot higher and as a result I,m finding that it slips down a little after a few miles. This might be due to there being less of the post in the frame, and my weight being a lot more at 94 kilos. Ile have a chat with the dealer when I pick up the orange bike tomorrow to see if he has had experienced this problem on other Tinkers. I will take the seat post along to compare the difference in length between it and the one on the new bike. I might consider swapping them to try the longer one at the higher height to see if it solves the slipping issue. If not I may have to consider changing the seat clamp or possibly adding a shim if that doesn't work. Have you experienced any problems in this area?
